WebStorm is a powerful JavaScript IDE and HTML editor that provides you with a large set of tools to help you create websites. The editor understands your code, its structure and offers you code completion that you expect. Full coding assistance is offered even for language mixtures such as HTML inside JavaScript strings. Hundreds of language specific code inspections analyse the whole project as you type and show you the identified problems before you open the browser. Intelligent quick-fixes offer instant solutions.

Support for cutting edge web dev technologies such as HTML5, Node.js, TypeScript, CoffeeScript, Dart, EJS, Handlebars, Mustache, Web Components, Stylus, LESS, Sass, Jade and JSLint/JSHint.

Key Features:

DOM-Based, Browser-Specific Completion:
JavaScript code completion for keywords, labels, variables, parameters and functions is DOM-based and supports popular browsers specifics (IE, Firefox, etc.) The completion is available for both standard and user-defined functions in *.js files, HTML event handlers and everywhere else where appropriate.
ECMAScript Harmony Support:
For those who prefer to stay one step ahead, WebStorm presents experimental support of a new ongoing ECMAScript version code-named Harmony. To try out new features, set ECMAScript Harmony to be the JavaScript language version in the IDE settings.
CoffeeScript & TypeScript:
Keeping pace with the newest technologies coming to the scene, WebStorm offers you CoffeeScript support 'hot off the press'. CoffeeScript is a programming language that compiles to JavaScript and enhances its brevity and readability, while also adding some sophisticated features like array comprehension and pattern matching. WebStorm offers you:
code navigation and completion
rename refactoring
syntax highlighting
error checking
find usages
automatic compilation/transpilation
debugging with sourcemaps
JavaScript Refactoring:
Refactoring capabilities provided for JavaScript allow you to easily modify the code structure as well as undo the modifications.
